文摘

A stable low gene expression in cytokinin metabolic pathway was identified in the dwarfing apple rootstocks. Support was found that methylation levels in the IPT5b promoter may contribute to dwarfing effect of M9 rootstock. Model of molecular mechanism for dwarfing effect in apple rootstock was proposed.
